Minneapolis police detective Sam Skarda, on leave after being shot, has been invited to participate as an amateur in the Masters golf tournament in this middling debut from sports writer Shefchik. Also visiting Augusta, Ga., is recently released convict Lee Doggett, out for revenge against the man who fathered but didn't raise him. When two people associated with the tournament are murdered in the first three days, club officials hire Sam to find the killer—quietly please, with minimal publicity. Because Shefchik reveals Doggett's identity and motive from the get-go, the payoff should be the edge of suspense to Sam's investigation—will Doggett harm more people before the police learn what the reader already knows? The unfolding of the investigation, when it finally gets going, however, is buried under a dense layer of Masters minutiae. Golfers may appreciate all the detail, but others may find it distracting.
